  • Patent number: 6096157
    Abstract: A cast coated paper for ink jet recording is prepared by a process including the steps of: forming on a base paper an undercoating layer containing alumina having a bulk density of at most 0.2 g/cm.sup.3 and an adhesive, applying onto the undercoating layer an overcoating liquid containing a resin to form a wet overcoating layer, and pressing the wet overcoating layer against a heated drum having a mirror-finished surface to dry the overcoating layer, thereby forming a cast-coating layer. The resultant cast coated paper shows not only good gloss and ink jet recording performances (inclusive of ink absorptivity and recorded image density), but also good weather-fastness of recorded images.
